by the form of the bill from Treron, and by the colour of the legs from 
Crocopus. 
There will be no difficulty found, I think, in discriminating the males 
of the four species of Osmotreron that occur in Burmah ; with the females, 
however, it is different, as they are all very similar. The following remarks 
may facilitate the identification of the females. The first two have the 
head green and the central tail-feathers ashy ; and whereas O. bicmcta has 
an ashy collar on the nape and hind neck, O. vernans has the whole head 
and neck green. In the other two species the head is grey and the central 
tail-feathers green ; and while in O. phayrii the head is pale bluish grey 
and the wing more than six inches in length, in O. fulvicollis the head is 
slaty grey and the wing less than six inches in length.
